Daily load curves

The consumption figures shown in the diagram are taken from real-time measurements of production units. These are raw data, and may be corrected subsequently. To view records of consolidated figures, click here.

The National Control Center (Centre National d'Exploitation du Système - CNES) constantly matches generation with consumers' power needs.

Electricity demand varies throughout the day and seasons. It is represented by a load curve, the forecast of which CNES draws up every day.

CNES makes sure that the generation schedules planned by the various power suppliers meet the total consumption requirements.

The diagram shows the variations in quarter-hourly points:

of French power consumption during the current day;

of the forecasts estimated on the previous day;

of the forecast estimated on the current day and generally published at 2.30 pm.

Any differences are mainly due to changes in weather conditions compared with the forecast data (temperature and luminosity).
